Brand new Keyed 3/4" bore split taper H bushing for pulley/sheave. This is a high quality steel bushing made for pulleys that require an H style bushing. This bushing inserts into the center of the pulley and slides over the shaft. As you tighten down the bolts on the H bushing it will tighten down on the shaft. This style is much more secure than a standard one piece pulley. This listing includes an H bushing to fit on a keyed 3/4" shaft.
